Think about c/3 =4/1 and apply the cross multiplication rule since those two fractions are equal.
We get c•1= 3•4
c=12
I am pretty sure the answer is 10. Someone correct me if I'm wrong
The angle of rotation of a polygon is found using the formula 360/n
Where n is the number of sides.
Shape 1: 360 / 10 = 36
Shape 2: 360 /4 = 90
Shape 3: 360 /5 = 72
Shape 4: 360/8 = 45
Shape 5: 360/3 = 120
Shape 6: circles = 1
Shape 7: 360 /6 = 60
Shape 8: 360 / 12 = 30
There are 3 shapes that are 72 or higher.
Y=1/4x is the correct answer
R(r+r^2)=(r)(r^2)
R^2+r^3=r^3
R^2=0
R=0
